Recently, I met three patients who had repeated shoulder dislocations during the consultation. They all dislocate the shoulder joint even when brushing their teeth, let alone exercising, which is very painful. At the time of surgery, it was found that the glenoid labrum of the shoulder joint were missing nearly 1/4, and the humeral head was missing nearly 1/5, making treatment very difficult and requiring 5-8 fixed anchors! The reasons for the delay in treatment were both on the part of the patient and on the part of the surgeon. Patients, and even most clinical doctors, are not sufficiently aware of it, and even oppose surgery, believing that it will not solve the problem. Or they believe that even if surgery is performed, it is done by incision and not only is it impossible to see all the diseased tissues clearly, but postoperative rehabilitation is also difficult. We must prevent from entering this misunderstanding! It is important to know that a very important cause of shoulder dislocation is a more or less significant defect in one’s own shoulder joint, and this defect can often be corrected, even once and for all, by simple surgical techniques. However, after repeated dislocations and injuries, this defect often multiplies and eventually leads to a large bone defect. This is why the Upper Limb Committee of the International Federation of Sports Medicine, of which I am a member, has unanimously recognized that arthroscopic surgery is necessary for first dislocations, or at least second dislocations, in people under 25 years of age, otherwise 80% of them will become habitual dislocations, and that for people over 30 years of age, only about 30% of first dislocations will become habitual dislocations. Generally speaking, for a first dislocation or a shoulder dislocation with little bone loss, the surgery takes about 30 minutes and only 1-2 fixation points are needed for a good repair, which is relatively inexpensive; however, recurrent dislocations require at least 4 fixation points (international statistics show that 3 fixation points are significantly higher than 4 in the future) or even the latest double row of 8 fixation points, which doubles or even multiples the cost and makes it significantly more difficult. Of course, the operating time for more complex shoulder dislocations by skilled surgeons is usually around 60 minutes. Therefore, we need to pay enough attention to shoulder dislocations. It is also important to emphasize that shoulder arthroscopy is a completely different concept than incisional surgery! Arthroscopy is not only minimally invasive, but incisional surgery is absolutely impossible to see the lesions behind the shoulder joint, and it is even more difficult to deal with the posterior humeral head defect after repeated dislocation of the shoulder joint, so there is a consensus at home and abroad that —- shoulder arthroscopy is the best way to deal with shoulder dislocation. However, at present, it is very difficult to master shoulder arthroscopy completely and comfortably, and it requires a high level of brain-eye-hand skills, so there are only a few doctors in China who can really master shoulder arthroscopy! Therefore, most doctors only use incisional surgery, but if the case is properly selected and the incision is done well, it is possible to achieve better results. In short, an arthroscopic field of view with a magnification of 5 to 50 times allows for a clear view of all the damaged tissue! Just as the knee meniscectomy is currently completely replaced by arthroscopy, I believe that in the near future, after our efforts, shoulder arthroscopy will be completely replaced by arthroscopy when it becomes popular!
